W2K Energy Options

Hy Foks,
I need some help with a script to modify the currend Energieoptions.
I want to deploy the pakage with a distribution tool, so I do not have to take care about rights. Due to Spying I found several RegKeys to be modifiyed, but is is still not working properly. In a Forum about "saving money with energieoptions" I found an article, that its not possible to change the settings by the regkeys, instead I have to use the API.
Any Ideas?
